[deprecative]

> "It's regressive to use a fully-JS TypeScript syntax instead of using dozens of tools on top of regular TypeScript to achieve the same outcome" is quite a spicy take.

To be fair, "We are so invested in TypeScript we're dropping it!" is an equally astonishing take. It's language I'd expect from Google about any of their projects.

But that's the thing, it's _not astonishing_. It _would_ be astonishing if we were abandoning typing Svelte. We're not. We're not even abandoning TypeScript -- the whole project will still run `tsc` and enforce complete type-safety, it just won't use the compiled output. This is _abandoning one syntax for another_ because one syntax doesn't require a build step and a huge toolchain to run and debug.
